Specification of Letters Patent.

Patented An 31, 1915.

Application filed June 4, 1914. Serial No. 842,925.

To all whom it may concern Be it known that I, LEONARD MAooMBnn, a citizen of the United States, and resident of lloston, in the county of Suffolk and State of Massachusetts, have invented certam new and useful Improvements in Finger-Nail Buffers, of which the following is specification. This invention relates to finger-nail buffers and consists in the several improvements hereinafter described and claimed and illustrated by the accompanying drawings. On the drawings: Figure 1 represents a side elevation of a buffer embodying my invention: Fig. 2 represents a top plan view of the buffer. Fig. 3 represents a longitudinal section of the same. Fig. d represents an inverted plan view of the base of the buffer. ig. 5 represents a transverse section as indicated by line 55 of Fig. 3. In Fig. 5, however, the parts are slightly separated in order to show the mode of assem'bling.

The same reference characters indicate the same parts wherever they occur. The structure as shown comprises a hard rigid base member 10, a soft cushioning element 11, a clamping ring 12, a cover plate 13, a handle 1-1:, and clamping devices in the form of screws indicated at 15, 15. The base and cushioning element 11 in conjunction with each other constitute the core or forming element which determines the contour of the attached sheet of flexible buff- The base 10 is formed with a laterally extending marginal flange-10, which coacts with an inwardly extending flange 12 formed upon the clamping ring 12, those two flanges coasting to clamp the of a sheet of suitable buii 111g material 16, such as chamois skin. The term ring as used in not intended to imply a circular shape but is intended to imply continuous, endless for-. mation, the clamping member 12 designated by the term ring being formed and arranged to surround the base 10. The ring 12 is provided with tapped holes 17 to re ceive the shanks of the clamping screws 15. These screws extend loosely through the cover plate 13 and their heads act upon the cover plate to draw the cover plate and clamping ring toward each other when the screws are set up tightly. The cushioning element 11 may be made of anysuitablesoft clamping screws 15 this specification is material, such for example as sponge rubber, and it is fastened to the base 10. In the present instance I have not shown fastening means but have relied upon glue to hold the contacting faces of the base and Cushioning element in the relation shown.

The structure as shown and described is designed to facilitate the renewal of the buffing material 16. In order to attach a sheet of buiiing material, the screws 15 are removed and the ring 12 and cover plate 13 are detached from the base. hen the sheet of balling material has been placed between the working surface of the cushioningelement and the dctachedring, onward movement of the ring places the marginal portionfo-f the buffing material so as to surround the flange 10 of the base. The flange 12 of the ring fits so closely that it draws the bufling material firmly against the cushioning element 11 when the ring is being moved to clamping position. The ring may be held upwardly against the flange 10 with one hand while the fingers of the other hand draw the edge of the bufiing material upwardly if it be desired tofurther tighten the bu'liing' material. It is to be understood that, in order to work the buffing material tight against the cushioning element, the sheet of bufling material will be larger than what is shown and that the excess butting material which. will project above the flange 10 is to be trimmed, as with scissors, so that its edge will be substantially flush with the top surface of the base, as shown. After the butting material has been trimmed as last stated, and while the clamping ring 12 is frictionally held in clamping position, the cover plate 13 may be set in place and the may then be inserted and set tightly. The flanges 10 and 12 are right-angular flanges, their surfaces being at right angles to each other, and they produce two right angular bends in the buihng material. The buffing material, being firmly clamped against two right-angular edges, is more securely held than if it were engaged by only one edge. This is a very desirable feature of the structure, as it avoids the likelihood of the bufling material becoming loosened inconsequence of its wiping action upon the finger nails.

As shown by Figs. 8 and 5, the top surface of the base 10 is above the top edge of the clamping ring. Inconsequence of this any downwardly to flange overlaps the marginal portion of the clamping ring and covers the gap between the clamp ng r ng and cover plate. This formation gives thecover plate and clamp ing ring .the characteristic relatlon of telescoping members.

a pulsating pressure upon Another feature of the invention is the contour of the working surface of the cushioning element 11. As shown by Fig. 3, this contour includes a series of wavelike formatlons. I am aware that nail buffers have hitherto been formed with a single-conoaved contour; but so far as I am aware this is the first instance of a nail bufler having a series of wavelike formations. One advantage of providing a series of such formations is that the inclined surfaces of the butting material are brought more frequently into contact with thesi de portions of the finger nail. In using my bufler it is not necessary to tilt the 'same'from side to side, nor is it necessary to rock the finger nail undergoing treatment in order to buff the side portions of the nail. A simple longitudinal reciprocating -movement is sufficient to buff substantially the entire surface of the nail. The series of protruding portions indicated at 18 produce the nail,which is desirable as it gives a massaging effect which is both pleasant and beneficial.

, I claim:

1. A finger nail butter comprising cooperative clamping members one of which is formed to surround the other, said members having coactive laterally extending flanges arranged to clamp between them the marginal portion of a sheet of flexible buffing material, and means to draw one of said members relatively to the other to effect clamping action of said flanges.

2. A finger-nail bufler comprising co6perative clamping members one of which is formed to surround the other, saidmembers having coactive laterally extending flanges arran ed to clam between them the mar-v ginal portion of a sheet of flexible bufling Copies of this patent'may be obtained for clamping members,

said cover plate and the outer one of said clamping members, said screws being arranged to cause clamping action of said clamping members.

3. A finger-nail buffer comprising cooperative clamping members one of which is formed to surround the other, said members having ooactive laterally extending flanges arranged to clamp between them the marginal portion of a sheet of flexible bufling material, a cover plate adapted to be seated upon the back of the inner one of said clamping members, and screws connecting said cover plate and the outer one of said clamping members, said screws being arranged to cause clamping action of said said cover plate having a downwardly extending flange arranged to surround said outer one of said clamping members.

i; A finger-nail bufler comprising a base having an external laterally extending flange, a ring adapted to surround said flange and having an internal laterally extending flange adapted to underlie said flange of the base, the confronting laterally extending surfaces of said flanges being adapted to coact to clamp the marginal portion of a covering of flexible bufiing material, said base and ring having surfaces arranged to bend said covering over the edges of both of said flanges, and means coacting with said base and ring to cause clamping stress by said flanges.

5. A device of the character described comprising a working member having an undulatory working surface, and cooperative elements carried by said member and arranged to grip the marginal portion of a sheet of flexible bufling material to hold such bufling material upon said working surface, said gripping elements being arranged to permit such bufling material to be drawn therebetween to conform to said undulatory working surface while said gripping elements are holding such material.

In testimony. whereof I have aflixed my signature, in presence of two witnesses.
